Application November 21, 1952, Serial No. 321,915

6 Claims. (Cl. 110-18) This invention relates to new and usefulimprovements and structural refinements in incinerators, particularlyincinerators of the domestic variety which are used outdoors for burningtrash, vand the principal object of the invention is to provide anincinerator with smoke eliminating means so that the smoke is notobjectionable to neighbors of the home where the incinerator is used.

The above object is achieved by utilizing hot air passing through thesmoke stack of the incinerator for supporting or assisting combustion inthe incinerator, thereby resulting in combustion at higher temperatureswith very little smoke, if any, results.

Some of the advantages of the invention reside in its simplicity ofconstruction, its eflicient operation and its adaptability toexpeditious and economical manufacture.

With the above more important objects and features in view and suchother objects and features as may become apparent as this specificationproceeds, the invention consists essentially of the arrangement andconstruction of parts as illustrated in the accompanying drawings, inwhich:

Figure 1 is a perspective view of the invention;

Figure 2 is a vertical sectional view thereof, the same being takensubstantially in the plane of the line 22 in Figure 3;

Figure 3 is a horizontal sectional view, taken substantially in theplane of the line 3-3 in Figure 2',

Figure 4 is a top plan view of the invention on a reduced scale; and,

Figure 5 is a perspective view of the fire pot or burner pot used in theinvention.

Like characters of reference are employed to designate like parts in thespecification and throughout the several news.

Referring now to the accompanying drawings in detail, the inventionconsists of an incinerator which is designated generally by thereference character and embodies in its construction a verticallyelongated, substantially cylindrical jacket 12 accommodating aforaminous, cylindrical burner pot 14, the latter being disposedeccentrically in the jacket and in spaced relation therefrom, so as toafford a chamber 16 between the jacket and the pot, as is best shown inFigures 2 and 3.

A plurality of horizontal bars 18 extend transversely through the jacket12 and support the pot 14 which is removably positioned thereon, the pot14 preferably being provided with suitable handles 20 so that it may beconveniently installed and removed.

In addition, a rod 22 extends transversely over the jacket 12 above thebars 18 and is provided with a substantially semicircular intermediateportion 22a, the latter extending partly around the circumference of thepot 14 and afiording a seat for the pot, so as to prevent the pot fromshifting on the bars 18.

The bottom portion of the jacket 12 is provided with a pluraltiy of airinlet apertures or openings 24, as shown.

A smoke stack 26 surmounts the jacket 12 and includes an upper, tubularportion 26a and a lower frusto-conical 2,760,451 Patented Aug. 28, 1956base portion 26b, the latter having an out-turned'flange 28 at the basethereof.

This flange is connected by a hinge 30 to the upper edge of the jacket12, so that the entire smoke stack 26 may be swung to one side asindicated by the dotted lines 32 in Figure 2. In that position of thesmoke stack, the interior of the jacket 12 becomes accessible for thepurpose of installing or removing the pot 14. The smoke stack 26 issupported in its laterally swung position by means of an angulated brace34 which is rigidly secured to the jacket 12 and extends upwardly andoutwardly therefrom, susbstantially as shown.

A handle 36 is provided on the flange 28 of the smoke stack for thepurpose of operating the same, and also, a suitable screen 38 isprovided in the smoke stack between the portions 26a and 26b.

Finally, the invention contemplates the provision of a duct 40 which isin the form of a flexible tube and extends downwardly from an upperportion of the smoke stack 26 to an intermediate portion of the jacket12, wherein it communicates with the chamber 16.

The flexibility of the conduit or duct 40, of course, will permit thesmoke stack 26 to be swung laterally as shown in Figure 2, at 32, andwhen the apparatus is in operation, hot air passing through the smokestack 26 will be drawn through the duct 40 into the chamber 16 and willassist the combustion in the fire pot 14 so that the combustion willtake place at a comparatively higher temperature and little smoke, ifany, will result.

After repeatedly experimenting with the invention, I have found thatwhen dry material is being burned, no smoke results therefrom. However,if the material being burned is somewhat damp or moist, a little amountof smoke will be produced. This small amount of smoke, of course, is notobjectionable, since it is far less than would otherwise result if thematerial were burned in a conventional incinerator.

It is believed that the advantages and use of the invention will beclearly apparent from the foregoing disclosure and accordingly, furtherdescription thereof at this point is deemed unnecessary.

What is claimed as new is as follows:

1. In an incinerator, the combination of a vertically elongated jacket,a foraminous burner pot mounted in said jacket and spaced therefrom toprovide a chamber between the jacket and the pot, an upwardly extendingsmoke stack including a frusto-conical base portion hinged to the upperportion of said jacket at one side thereof to swing over and with itsbase in registry with the upper end of said jacket whereby to form aclosure for the upper end of the jacket, and a flexible conduit incommunication with the interior of and extending downwardly from theupper end portion of said smoke stack and communicating with saidchamber.

2. In an incinerator, the combination of a vertically elongated jacket,a foraminous burner pot mounted in said jacket and spaced therefrom toprovide a chamber between the jacket and the pot, an upwardly extendingsmoke stack including a frusto-conical base portion hinged to the upperportion of said jacket at one side thereof to swing over and with itsbase in registry with the upper end of said jacket whereby to form aclosure for the upper end of the jacket, and a flexible conduit incommunication with the interior of and extending downwardly from theupper end portion of said smoke stack and communicating with saidchamber, and means for removably supporting said pot in said jacket.

3. In an incinerator, the combination of a vertically elongated jacket,a foraminous burner pot mounted in said jacket and spaced therefrom toprovide a chamber between the jacket and the pot, an upwardly extendingsmoke stack including a frustoconical base portion hinged to swing overand with its base in registry withthe upper end of said jacket whereby"to form a closure for the upper end of the jacket and a flexible.conduit in communication with the interiorof and extending....downwardly from. the upp nd p rtion. of said. smokes aek' and communicating with said chamber, the lower portion of said jacket beingprovided with airjinlet openings.
